>>4734608there won't ever be a death of these kinds of phenotypes, not even red hair in the long run. if you were to reproduce with them you could still have kids with light characteristics. worst case scenario, tons of phenotype mixing goes on and they just become rarer, never extinct
I'm not sure if they're becoming rarer or more common today. obviously though, traits like these were considered attractive because of their rarity and that's why so many europeans have them today, so they did historically increase in frequency
